Jan 12 (Reuters) - U.S. stock futures fell on Friday after consumer prices in December posted their biggest gains in 11 months, raising expectations of inflation gaining momentum this year.
The Labor Department's Consumer Price Index, which excludes the volatile food and energy components, rose 0.3 percent last month. Economists polled by Reuters had forecast core CPI rising 0.2 percent.
Core CPI increased 1.8 percent in the 12 months through December, picking up from 1.7 percent in November.
"I don't think CPI data changes our impression about monetary policy. December was a mild disppointment in terms of retail sales, as it came a touch below expectations," said Art Hogan, chief market strategist at B. Riley FBR in Boston.
"But if there is any negative reaction to the data, it should get washed out as we open."
Another set of data showed U.S. retail sales increased in December and figures for the prior month were revised higher, suggesting that the economy exited 2017 with strong momentum.
The Commerce Department said retail sales rose 0.4 percent last month. Economists polled by Reuters had forecast retail sales increasing 0.4 percent in December.
